Flora of Cornwall (1999)

The descriptive text, below the map, is from the Flora of Cornwall (1999), which was a Tetrad Atlas (the maps had 2km square dots or Tetrads). The map on this web page depicts the plant's distribution at the 1km square scale and shows the records made pre-2000 which were used in the 1999 Flora and those made since.

Galeopsis angustifolia - Narrow-leaved Hemp-nettle

Nationally Scarce, Red Hemp-nettle is an arable weed normally found on calcareous soils. It is probably extinct in Cornwall and the last record from north of Trematon in the Saltash area (SX36V, 1970, D. Baster) was almost certainly a casual.
